【摘要】：随着我国环境污染问题的日趋严重,现在政府以《环境保护法》为有力武器,加大对环境污染的监督检查和处罚力度。大气污染是我国现阶段环境污染的主要成分之一。其主要表现是:以燃煤排放的烟尘和二氧化硫为主要污染物的大气污染;粉尘是大气环境中涉及面最广、危害最严重的一种污染物。中国大气污染主要是由燃煤造成的。主要污染物是烟尘和二氧化硫。末端治理仍是我国长期以来治理环境污染的一种基本手段。电除尘器是治理燃煤排放的烟尘的主要手段之一。随着电除尘器单台处理烟气量越来越大及排放浓度越来越小,电除尘器也越做越大,单台长、宽、高经常达到35×30×25米,其是大跨度空间结构设备,因此其单台钢耗量也越来越大,经常单台重量达到1000多吨,其单台造价也越来越高,因此要对电除尘器进行结构优化设计降低钢耗量,提高企业产品市场竞争力。针对电除尘器存在的问题,通过调研、分析、对比各种优化分析方法,本文采用STAAD结构计算分析软件对电除尘器结构的零部件进行了有限元分析与设计,并根据软件分析计算结果,对电除尘器的进气口、出气口、灰斗、电除尘器的底梁、进出气端端墙及顶梁等结构的主要承重部件进行了优化设计,优化结果表明,这样既增加了结构的稳定性又充分的利用了材料的性能,减轻了设备的重量,降低了成本,提高了产品性价比,提高了产品的市场竞争力。
[Abstract]:With the increasingly serious problem of environmental pollution in China, the government is now using the Environmental Protection Law as a powerful weapon. Air pollution is one of the main components of environmental pollution in our country at present. Its main manifestation is: air pollution with smoke and sulfur dioxide from coal combustion as the main pollutants; Dust is the most extensive in the atmospheric environment. The air pollution in China is mainly caused by coal combustion. The main pollutants are soot and sulfur dioxide. Terminal control is still a basic means of environmental pollution control in China for a long time. The dust collector is one of the main methods to control the smoke and dust from coal combustion. As the amount of flue gas is increasing and the emission concentration is becoming smaller and smaller by the single ESP, The electrostatic precipitator is becoming bigger and bigger, with a single length, width and height of 35 脳 30 脳 25 meters. It is a large span space structure equipment. Therefore, its steel consumption per unit is also increasing, and the weight of a single unit is often more than 1000 tons, and the cost of a single unit is increasing. Therefore, it is necessary to optimize the structure design of ESP to reduce steel consumption and improve the market competitiveness of enterprise products. In view of the problems existing in ESP, through investigation, analysis and comparison of various optimization analysis methods, In this paper, the finite element analysis and design of the structure parts of the electrostatic precipitator are carried out by using the STAAD structure calculation and analysis software. According to the results of the analysis and calculation of the software, the air inlet, the outlet, the ash hopper and the bottom beam of the electrostatic precipitator are analyzed. The optimum design of the main load-bearing parts of the structure, such as the end wall and the top beam, is carried out. The optimization results show that the stability of the structure is increased, the performance of the material is fully utilized, the weight of the equipment is reduced, and the cost is reduced. Improve the product price-performance ratio, improve the market competitiveness of the product.
